If you are looking for high-quality stainless steel tubing that meets stringent hygiene standards and is suitable for the food, beverage, and pharmaceutical industries, we offer ASTM A270 TP304 3A Stainless Steel Sanitary Tubing, specifically designed for high-purity fluid transfer systems, dairy processing equipment, and pharmaceutical process piping.
Our TP304 3A sanitary stainless steel contains 18–20% chromium (Cr) and 8–10.5% nickel (Ni), and undergoes precision cold rolling and pickling treatment. It meets 3-A sanitary standards, boasts a high surface finish, with inner and outer diameter surface roughness typically Ra ≤ 32 microinches (0.8 micrometers) or lower, usually achieved through 180-240 grit polishing. This minimizes the risk of microbial growth.
Our ASTM A270 TP304 Sanitary Tubing is available in a variety of sizes, with outer diameters ranging from 6mm to 168.3mm, uniform wall thickness, and customizable lengths. To guarantee product quality, each tube undergoes MTC (Material Test Certificate), dimensional inspection, inner and outer surface finish inspection, and non-destructive testing (UT/PT), ensuring compliance with 3A, ASTM A270, and relevant FDA standards, making it suitable for demanding sanitary piping systems.
